To all whom 2'25 may concern: 7

Be it known that I, CLEMENT WV. MICHAEL, a citizen of the United States, and a resident of Racine, county of Racine, and State of Wisconsin, have invented certain new and useful Improvements in Plows, of which the following is a full, clear, and exact description.

The invention relates to plowsand seeks to provide an improved combined colter and join'ter for the plow in which means is pro,- vided for yieldingly pressing the jointer blade against the face of a revolving colter, so that trash cannot readily accumulate between these parts.

The invention consists in the features of tion of the plow with the present improve,

ment applied thereto. Fig. 2 is an enlarged elevation of the revolving colter, colter support and the jointer blade.

Fig. 2. Fig. 5 is a detail section on the line 55 of Fig. 2.

The plow body 10 is mounted; as usual, upon the rear end of a beam 11. A flat, circular, revolving colter 12 is mounted upon a suitable support in front of the pl owhody.

The present improvement may be applied either to a walking or riding plow, butthe construction shown is more partie ularly applicable to a riding plow. In this construe; tion, the support 13 whereonthe'revolving" colter is journaled is fixed, at its upper p'ortion, to the rear end of an arm 14.. This arm is pivotally connected at its forward.

end to the lower end of a standard 15 that is secured to the plow beam. H

The standard 15 maybe secured to the beam in any suitable manner. In the construction shown, its upper end is fixed in a clamp 16 which abut-s against one side of the beam. The clamp is held in position by two bolts 17 which abut against the upper and lower edges of the beam and extend through lugs on the clamp and through the ends of a strap 18 which abuts against the opposite side of the beam. By this means, the position of the clamp on the beam may be adjusted to move the colter to and from Fig. a; horizontal section on the line 33 of Fig.2, Fig. -IL is a rear view ofthe parts shown in the plow body. A collar 19 is securedby a set screw 20 to the lower end. of the standard 15. The forward end of the arm 14L is provided with hub portions, 21 which engage the lower end of the standard on opposite sides of the collar 19. The arm 14 is thus swiveled to the standard.

The arm 14 is provided with a clownturned rearend and the upper portion of the colter support 13 is fixed thereto by a pair of bolts 22. Two holes are provided in the support 13 ;for the'upper one of these bolts, so that the position of the colter support maybe adjusted. At its lower end, the colter support is provided with a boss 23 which extends throughacentral opening in the colter; and the reduced inner end portion 2 1 of this .boss extends within the bore of a colter, hub 25. This hub is provided on its inner end with a flange 26 that is riveted to the colter blade andj'onv its inner face the hub has acircular rib 27 thatfits within the central opening in the colter blade. A sleeve 28 fits within the bore of the hub and is provided at its outer, end with a flange 29 which overlaps the outer end of the hub. This sleeve is fixed in position tohold the colter in.place by a bolt 30 which extends therethrough and which, at its inner end, is threadedinto the boss; 23 on the colter support. A cap piece 31 .is threaded upon the hub 25 and extendsover the outer end thereof airdforms a cup for retaining lubricating material. The inner end of the bore of the'hubis preferably enlarged to receive a feltwasher 32. which held in place by a steelwasher 33 interposed between the ad jacent faces of the colter and colter support. The felt washer 33 prevents the entrance of dirt ,into the colter bearing. understood, however, that the colter bearing mayjbe otherwise constructed without de parture from the essentials of the present invention.

The colter support 13 is provided on its outer face with a frog3t which is preferably cast integral therewith. A jointer blade 35 is" pivotally mounted "uponthe face ofthefrogi As usual, the face of the jo-inter blade is curved in a manner similar to that of a plow body and preferably the point and moldboard portion of the plate are formed of a single piece of hardened steel. The jointer blade is secured to the moldboard by an upper pivot bolt 36 and a lower fastener bolt 87. The heads of these bolts are set into the face of the jointer blade, extend through short sleeves 38 and at their inner ends are provided with nuts 39 and washers 40 which bear against the ends of the sleeves 38. The sleeve 38 of the upper pivot bolt 36 tits in a round hole in the frog 3st while the sleeve 38 of the lower fastener bolt 37 eX- tends through a laterally disposed slot t1 in the frog, so that the blade can swing to a limited extent about the upper pivot bolt 36 to and from the adjacent face of the revolv ing colter The bolts and 37 securely hold the blade in position upon the face of the frog, but permit the pivotal movement thereof over the face, since the sleeves 38 are slightly longer than the thickness of the frog.

A spring is provided for yieldingly holding the lower pointed end of the jointer blade snugly in engagement with the face of the colter 12. Preferably, as shown, a cushion spring at? is provided on. the rear face of the frog. This spring extends between a lug 43 on the frog and one end of a lever ltfij which is pivoted between its ends to the rear face of the frog by a bolt 45. The lower end of the bolt bears upon the nut 39 on the lower fastener bolt 37 so that the lower pointed end of the jointer blade is yieldingly pressed against the face of the colter.

The jointer blade 35 is of course arranged on the furrow side of the colter and the latter is preferably beveled at its edge on the land side only, so that its entire furrow side is flat and the lower end of the joint-er blade can make snug contact therewith at a point near its edge.

In operation, the sod and trash are out along the line of the furrow by the colter and a portion thereof is turned over in advance of the plow, so that all trash and sod are Q'tfGCtlVGly covered when the plow body completes the furrow. The lower end or point of the pivoted, spring-held jointer blade maintained in snug engagement with the face of the colter and follows any slight irregularities in the movement of the colter due to the wear or adjusti'nent of its bearing. -With this construction, trash cannot readily accumulate between the colter and the ointer blade to check the revolution of the colter and thereby prevent its effective operation. The entire inner edge of the jointer blade is arranged closely adjacent the face of the disk, but is preferably inclined slightly away from this face, as shown in Figs. 3 and at, so that any trash caught between these parts may work out.

It is obvious that changes may be made in the details set forth without departure froin the essentials of the invention as defined in the claims.

I claim as my invention 1. In a plow, the combination of a flat, revolving colter, a support whereon said colter is journaled, a frog on said support, a jointer blade pirotally mounted on the face of said frog, and av spring for yieldingly pressing said jointer blade against the face of said colter, substantially as described.

2. In a plow, the combination of a flat, revolving colter, a support whcreon said coltcr is journaled, a frog on said support, a jointer blade mounted on said frog and abutting against the face of said colter, a pivot bolt connecting the upper portions of said jointer blade and said frog, a lower fastener bolt connecting said parts, said frog having a slot through which said lower fastener bolt extends, and a spring for pressing the lower pointed end of said jointer blade against the face of said revolving colter, substantially as described.

In a plow, the combination of a fiat, rcvol ving colter, a support whereon said colter is journaled, a frog on said support, a jointer blade pivotally mounted on the face of said frog, a part connected to said blade and extending through a slot in said frog. and a spring device on the rear face of said frog and engaging said part to yieldingly press said jointer blade against the face of said revolving colter, substantially as described.

4t. In a plow, the combination of a flat revolving colter, a support whereon said colter is journaled, a frog on said support, a jointcr blade mounted on the face of said frog, a pivot bolt connecting the upper port-ions of said jointer blade and said. frog, a,lower fastener bolt connecting said parts. said frog having a slot through which said fastener bolt extends, and a springpressed arm mounted on the rar face of said frog and engaging said fastener bolt for yicldingly pressing the lower pointed end of said jointer blade against the face of said revolving colter, substantially as described.
